Class VersionNumber

java.lang.Object
  hudson.util.VersionNumber

All Implemented Interfaces:

Comparable<VersionNumber>

public class VersionNumber
extends Object
implements Comparable<VersionNumber>

Immutable representation of a version number based on the Mercury version numbering scheme. VersionNumbers are Comparable.

Special tokens

We allow a component to be not just a number, but also "ea", "ea1", "ea2". "ea" is treated as "ea0", and eaN < M for any M > 0.

'*' is also allowed as a component, and '*' > M for any M > 0.

'SNAPSHOT' is also allowed as a component, and "N.SNAPSHOT" is interpreted as "N-1.*"

 2.0.* > 2.0.1 > 2.0.1-SNAPSHOT > 2.0.0.99 > 2.0.0 > 2.0.ea > 2.0
 

This class is re-implemented in 1.415. The class was originally introduced in 1.139
